Management of meloidogyne incognita race 1 through the use of entomopathogenic nematodes in tomato

Entomopathogenic nematodes; steinernema asiaticum (anis),steinernema glaseri (steiner),heterorhabditis indica (poinar) and heterorhabditis bacteriophora (poinar) were investigated for their effect on meloidogyne incognita (kofoid and white) in tomato. they were applied at different levels before and at the same time with the application of root-knot nematodes. suppression of m. incognita varied with application rates of s. asiaticum,s. glaseri,h. indica and h. bacteriophora in tomato. the high application rates of s. asiaticum,s. glaseri,h. indica and h. bacteriophora applied both at the same time and before reduced m. incognita egg production. the low rates of s. asiaticum,s. glaseri,h. indica and h. bacteriophora were not as effective as high application rates. the findings of this study suggested that entomopathogenic nematodes could be used for the management of root-knot nematodes.
